The Lowdown
Alright, Rusty here, and I’ll be straight with you – the next couple weeks at Kennebunk Beach are going to test your patience.
The overall pattern for the 16-day window starts flat and stays marginal for a long stretch. There’s nothing worth paddling out for from Monday, August 24th, all the way through to the start of September. That’s over a week of weak, short-period windswell in the knee-to-thigh high range, with mostly cross-onshore or choppy conditions. The combined swell energy barely gets into the triple digits early on (114 to 120), and that’s just not enough push to make it fun.
We finally see a change on the morning of Wednesday, September 2nd. The wind goes completely glassy (calm), and the swell bumps up to 0.9m (about 3 feet) from the southeast with a long period of 13 seconds. The combined energy jumps to 340 (moderate). The waves will be clean and glassy that morning – surfable but nothing to write home about. It’s a small groundswell, and since it’s a sheltered beach setup, the long period could make it a little straight, but it’s a welcome break from the flat spell.
The true standout is the morning of Thursday, September 3rd. That’s the one to circle on the calendar. We’ve got 1.4m (about 5 feet) of southeast swell with a very long period of 16 seconds, and the combined energy hits a strong 1658. The wind is glassy out of the northeast at just 5 km/h (about 3 mph). This is the best surf of the whole outlook – clean, solid chest-high waves, good energy, and the long period will produce proper lines. This is the day for experienced surfers to go early. Kennebunk Beach is a sheltered spot, so the long period groundswell should wrap in nicely. Crowds are sometimes an issue, and with a good swell like this, expect a few locals out.
After that, Thursday afternoon sees a bit more wind and some light rain, and the quality drops. Friday the 4th is back to smaller, weaker surf with cross-shore winds. The rest of the outlook fades into knee-to-ankle high mush through the second week, with the only real highlight already behind us.
Water temp at Kennebunk Beach is about average for late August / early September – no major anomaly, so no need to dig out the 5/4 just yet.
Bottom line: the first week is a write-off. Make plans for the morning of September 3rd – that’s your best shot for clean, legitimate waves.
Rusty.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
